阅读《笑面人生是幸福》,回答问题。
        生命的进程中,常常会遇到许多问题,凡属问题,多多少少会影响到自己的心境,于是,悲哀有之,伤感有之,郁郁有之,压抑有之,嚎啕更有之。这种情况,在我看来却是大可不必。
        人生重要的是活出生命的精彩,把生命的意义发挥的淋漓尽致,不管是发生了什么事,首要的是处理问题的方式方法和态度,决不是如遭灭顶之灾或无病呻吟。生命就是斗争,与天斗,与地斗,与人斗,斗争中无可避免会受伤和毁灭,面对困难和挫折,遇到打击和伤痛,只要面向阳光,就不会陷于阴影,所以要笑面人生。
        这世界,大自然,社会存在许多哲理,需要随时去体会,去感悟。世间万事万物都是相辅相成的,这是矛盾,也是哲理,因此,即使有一时的让人难以承受的痛苦和磨难,也不会是毫无意义和价值,至少,它可以使我们吃一堑长一智,让意志更坚定,思想和人格更成熟。当下一个困和挫折到来时,就会更平静地面对,更乐观地去处理。
        笑面人生,要有一份超然。当好心不得好报时,要豁达。当有人颠倒黑白时,也无须在意。对待命运也一样,人活世间,本来就有高低贵贱,人生有如一树花开,同发一枝,随风而逝的景况不一,有坠于绿茵,或掉入污泥,贵贱殊途,因果勿思。存在就是合理,合理就是美丽,这是自然法则,也是生命的定律。
        笑面人生,应会适时抽身。人生走错路的时候有很多,走错了没关系,只是千万别一条道走到黑。俗语也说“不要只在一棵树上吊死。”道理相同,不要舍不得抽身而退,不要心存幻想和侥幸。孔子曾叹:“尺蠖(huò)之曲,是求伸也。”一张一弛,文武之道,收回拳头,再打出去才会更加有力。
笑面人生,无妨偶尔认输。对一些难以纠缠的麻烦,认输也没什么可惜。比如失恋,就当是患了一次感冒,即使是重感冒,也不过如此,一时的痛苦难免,但伤痛欲绝,哭哭啼啼又是何必?这世界最不缺的就是人!不属于你的,就不应该去可惜,即使是应该属于你,但得之,我幸;失之,我命。塞翁失马,焉知非福,也许,人生下一个驿站,有一道更美丽的风景。
        所以,别去置身于无谓的我是人非的旋涡,更不要在尔虞我诈中摩擦。人,虽不能决定自己生命的长短,但完全可以扩展生命的宽度、深度和广度。虽不能改变自己的容貌,但完全可以时时展现灿烂的笑容,而世间万事万物只有笑容最美!只要掌握好自己,充分运用好今天的一切,幸福就是不远的距离。
       人,必须豁达大度,才不至于钻入死胡同或牛角尖,才能乐观进取,才能站得高看得远;豁达才有大度,才有严于律己,宽于待人,从而自己开朗,快乐也带给了别人,生活的氛围就充斥处处着愉悦的温情。郁闷是因为想不开,拿不起,放不下,心有千千结,无心之事,有意接受并堆积于心,一生中心情灰暗,天地失色也就在所难免!试问,这种活法,又会幸福到哪去?
       幸福原本就这么简单,不在于拥有多,而在于计较少!计较多,是负担,是一种意义的失;计较少,也非不足,而是另一种程度上的余;舍也不是弃,弃也不是无,而是另一意义上更宽广的拥有和拾取。
        生命中应时时让自己拥有一颗轻松自如的心,一份乐观豁达的心智,不管风起云涌,不管世事变化和沧桑变迁,拥有一片属于自己的满足而宁静的天空,才会有笑面人生的永恒!

The CLF Art Cafe, Peckham

    Playing different kinds of music, it has a night to serve most tastes. As one of the leading places for the creative arts, the building is full of friendly but crazy students and young people devoted to having a good time. But for those who aren't interested in making the ceiling sweat, there is an open-air rooftop, monthly plays and regular showings of films.

    Roxy, Fitzrovia

    In the heart of London's shopping center lies one of the flagships for a student night out in London. After showing their Student IDs, students head down into the basement (地下室) of the Roxy where they are thrown into a group of young people from all backgrounds and countries. Whether for a few drinks and a chat or a dance along to the sound of the latest hits, the Roxy's half-priced cocktail (鸡尾酒) will make sure you are satisfied.

    Bar Kick, Shoreditch

    For students who are very busy and have forgotten how to relax, keep yourself focused while you play a game of table football. Put yourself into the crowd of bars and clubs Shoreditch has to offer, Bar Kick presents students with a quiet evening. At street level, it seems like any other bar. Heading downstairs you'll find almost a dozen football tables replacing the dance floor, giving it a competitive edge to an evening away from school work.

    The Court, Tottenham Court Road

    For an affordable meal and drinks on a Sunday before a week of stress, head over to The Court. Combining the perfect combination of traditional pub comforts with student prices, the central London pub offers a quiet place as you catch up with classmates and forget about the stresses of being a student,
